The 115-year-old plant on the banks of the San Antonio River will be shuttered April 29, Pabst chief operating officer Jim Walter said.

Walter said 82 employees will be laid off, but about 100 corporate and administrative employees will continue to work in the complex. Pabst has another brewery in Lehigh Valley, Pa., and produces several brands of beer under contracts with other brewing companies.

Since June, when San Antonio-based Pabst's board of directors voted to keep Pearl open with a skeleton crew for at least three more years, production has been cut from 1 million barrels a year to 50,000 barrels.

In July, more than 260 employees were laid off.

The remaining workers have continued to make Lone Star and Pearl, two regional beers born in San Antonio. Production of higher-volume beers was moved to Fort Worth under a contract with Miller Brewing Co.

Walter said continuing operations at the old plant was cost-prohibitive.

''It's not a real efficient brewery, so it takes a lot of manpower to produce the products,'' he said.
